Diatrypaceae on Trachycarpus

I'd like to know your opinion on this fungus which may belongs to the family Diatrypaceae, which forms gregarious stromata as very slightly raised plates on the epidermis of the rachises of Trachycarpus fortunei (Arecaceae). More or less longitudinally arranged and delimited by very irregular black lines, with a melanised surface and an unchanging entostroma containing very sparse perithecia in an eutypoid arrangement, with a diameter ranging from 350 to 500 µm, with short necks opening outwards through slightly prominent and almost always cruciform small ostioles.Asci with long pedicels, Mlz. and IKI markedly positive.
I do not know whether it could belong to the genus Eutypa, Diatrype or another genus which I am not considering.
Many thanks in advance

Re : Diatrypaceae on Trachycarpus
Hola Enrique,
I agree with you Eutypa should be the closest genus to accommodate your fungus.
I found nothing matching it, but Trachycarpus being a Chinese palm, it may have travelled with its saprophytes.
I checked in vain the recent Chinese papers on Diatrypaceae, those I have at hand, but morphological descriptions are often lacunar. Comparing an ITS sequence of your collection to those they published might provide a lead.
Again not very helpful to you, sorry.
Best,
Jacques

Re : Diatrypaceae on Trachycarpus
Unfortunately we don't always have answers to our questions, it's one of the punishments of our species. But you are always tireless in trying to answer many of the questions I ask myself.
Thank you very much for your efforts and also for your knowledge.
